Power Flow Control of Interconnected AC-DC Microgrids in Grid-Connected Hybrid Microgrids Using Modified UIPC

Abstract

A typical grid-connected hybrid microgrid has one AC microgrid and one DC microgrid, which is considered for this system. Alternate of deploying the parallel-connected power converters, these microgrids are having all constituent parts linked deploying to make partial changes UIPC. The traditional construction of UIPC, which conveys three power converters in each stage, is rolled out incomplete improvements so the check of power converters is executed for power trade control between AC-DC microgrids. The substitute situating involves one power converter in each stage, named as line power converter, and transport power converter. The AC microgrid is united to the main grid into the LPCs which their DC transports are related and can set off in capacitance mode. A fuzzy regulator is conveyed in the lead representative development of the LPCs. The fuzzy framework is registered dependent on H∞ separating strategy to diminish the mistakes in enrollment capacities design. From start to the completion the BPC, the DC voltage of LPCs is contributed by the DC microgrid. Nonetheless, since the DC microgrid voltage is on condition that here by a PV framework, the DC interface voltage of the LPCs is rising and falling sporadically in number. Subsequently, as the beneficiation to hold consistent the DC connect dissimilarities, another nonlinear unsettling influence eyewitness based powerful different surface sliding mode control game plan is administered for DC side control of the BPC. The results build up the adequacy of the set forward power stream control approach of the improved UIPC for mixture microgrids.
